If you are running your blog on WordPress.com, the site that hosts Free Blogs for you, and want to move it to your personalized domain, read this post.
You can now use your own custom domain with your WordPress.com blog. For example, if your blog was currently at example.wordpress.com you could buy example.com from us and we would automatically move your blog over and redirect all your links and readers to the new domain.
How does this work? Well to get started, first log in to your WordPress.com account, then go to Options > Domains. You can enter the domain you want in the box at the top. See the pic below.
If the domain isn’t registered, it will ask you for some information and then register it for you, and add domain mapping, for $15/yr.
If you already own a domain you registered somewhere else, you can map it for $10/yr. The next screen will tell you how to change the DNS nameservers on your domain to point to WordPress, and once you do that your domain should be live within a few hours.
